Hi Harald
I understand your concerns around these memory leak issues. As you know,
the Weld team is addressing these issues through WELD-570. The upcoming
1.1-BETA1 release of Weld (which should be integrated into GlassFish 3.1
trunk after it becomes available) has a new javassist integration and
also proxy classloading changes that should address WELD-570 and
GlassFish issue 12368. Hopefully with these changes, the memory
footprint of your application should look better. I will test and update
my observations in 12368 after the integration.
Thanks
--Siva.
